Lore

Also known as Elfriede, Sister Friede was the first Ash to enter the painting, but together with the good Father, they "chose rot over fire". She wields a great scythe, which in the painting world is a symbol of a long-lost home, possibly explaining her preference for it.

Friede's sister (perhaps figuratively) Yuria laments her as "A poor wench turned to Ash, who would abandon Londor". After renouncing everything, Friede discovered a people that she wished to protect, and assumed the precise form that they yearned for.

Theories

The Chillbite Ring

At some point in her past, Friede was due to receive a special ring, either to commemorate her station or possibly as a token of betrothal, but "this ring would never grace [her] hand, for the painting and it's frost became her home."

Dialogue

Welcome. To the painted world of Ariandel.
I am Friede. I have long stood beside our blessed Father, and the rest of the Forlorn.
But Forlorn thou seemeth not.

Lord of Hollows, I know not the missteps which led thee to this painted world.
But they duty is all, and thy duty lieth elsewhere.
Return from whence thouh cam'st.

I presume it visible to thee? The bonfire here, in this room.
A meek and faded thing, but 'twill guide thee nonetheless.

Upon Giving Chillbite Ring

Ahh yes, there is a thing thou shouldst by rights possess.
A remembrance of this cold world, for the great Lord of Londor.
May it help thee bear they duty.She hands you the Chillbite Ring
Now, return from whence thou cam'st.

Upon opening Shortcut

Be forewarned, eager Ash,
Should this world wither and rot,
Even then would Ariandel remain our home.
Leave us be, Ashen One.
Thou'rt the Lord of Londor, and have thine own subjects to guide.

Upon triggering Boss Fight

Fear not father, we have no need of thy flail.
Tis only the flame, quivering at misguided Ash.
Please, avert thine eyes.
I will snuff out these ashes for good.

During Fight

Return from whence thou cam'st
For that is thy place of belonging

Return from whence thou cam'st
Yuria surely awaits thee.

Leave us be, Ashen One.
Sweep all thought of us from thy mind. As thy kind always have.

Leave us be, Ashen One.
Thou art the Lord of Londor and have thine our subjects to guide.

Friede's Great Scythe
A great scythe wielded by Sister Elfriede, with a curved blade thinly coated by Painted World frost that easily breaks the guard of shields.
In the painting, the scythe is a symbol of a long-lost home, possibly explaining Elfriede's preference for it.

Skill: Elfriede's Stance
Conjure a magic bladed support scythe into the left hand while the great scythe remains in the right, a stance derived from Elfriede's former swordmanship. Use normal attack to leap forward and swing twice, or strong attack to coat the earth with running frost.

Chillbite Ring

Yuria of Londor DialogueWith Friede's soul in your inventory
"Ahh, our Lord and Liege. Twas the soul of my sister. Elfriede…
A poor wench turned to Ash, who would abandon Londor…
If thou wouldst, let it nourish they Lordship.
And in return, do her one small kindness.
Remember those who stayed by her to the end, in the shadows cast by fire…
And lastly, my Lord, take up thy rightful mantle, of usurper."
